[MlMt] filter/smart folder by 'state'

[Jason Davies]

Hi everyone

Short version: Is there a way to create a rule or smart mailbox for 
things via the 'state' column's information?

Long version: for reasons we can't avoid, I end up with duplicate 
outgoing mails. The only discernible difference is that one says 'Sent 
via [my address]', visible if I select 'state' in the Column view. But I 
can find no way to use this; even clicking on the heading doesn't sort 
them by 'state'.

The list of criteria for rules has various things for 'state' but 
they're all specific to other things. Is there a way to automatically 
get these messages?

Cheers,

Jason
